The present research deals with the taxonoy of the genus Eremogone, using morphology of seed; the species occurring in Türkiye are examined. Nineteen characters (qualitative and quantitative) were observed or measured using light microscopy and Scanning Electron Microscopy; statistical analyses considered are PCA and Clustering. The average length of Eremogone seeds was 1756 μm (1168–2569 μm), and the average width was 1148 μm (866–1674 μm). Seed shape, based on the seed length-to-width ratio, ranged from spherical to prolate spheroidal. Seed colors varied from yellowish-brown to dark brown-black. The seed coat surface was covered with tubercles, and the dorsal surface of the seed was covered with papillae ranging from 27 to 146 in length. The identified potential characters contribute to the delimitation of the Turkish species of Ermogone; a diangostic key is proposed.

The palynological characters of 17 taxa belonging to genus Eremogone Fenzl (Caryophyllaceae) from Türkiye were examined using light microscopy and scanning electron microscopy. Eremogone pollen in Türkiye is found to have an average size of 31.31 μm (26.62‒36.65 μm), pore sizes ranging from 6.52 to 9.24 μm, inter-pore distances ranging from 9.07 to 12.57 μm, pore numbers varying from 5 to 14 and 5‒30 nanoechini distributed in an area of 10 × 10 µm. The ornamentation was identified as nanoperforate, nanoechinate, or nanofaveolate surface elements in various combinations. Clustering analysis and Principal Component Analyses do not show clear groups, although more similar taxa were brought together through the analysis of pollen micromorphological data rather, the nanoechinate base width, nanoechinate length, and pore diameter length are the most valuable variables for separating the examined taxa.
